MNP Class 2 : Java Glossary

Nearly all MNP (Microcom Network Protocol) modems have at least class 2 level support. Here the
modems use an asynchronous byte-at-a-time, full-duplex (simultaneous send-receive)
method. The protocol efficiency is about 84%. A 2400 BPS (Bits Per Second)
modem will realise a throughput of about 2000BPS.
